Description

Technical Field

[0001] This invention relates to the field of building material production technology, specifically to an aerated concrete panel production line system and method. Background Technology

[0002] Autoclaved aerated concrete (AAC) panels are a new type of energy-saving panel introduced under the national energy conservation and environmental protection policy. These panels not only improve the quality of building wall materials, but also save energy, protect the environment, and reduce product costs.

[0003] In the production process of this autoclaved aerated concrete (AAC) panel, the entire stack of panels (i.e., 1200mm high) is generally divided horizontally, that is, the entire stack of panels is divided into multiple pieces along the horizontal direction of the stack height, and then packaged and taken off the production line.

[0004] However, in the existing board production line process, it is usually necessary to divide the whole stack of boards into two half stacks (i.e., 600mm high), pack the two half stacks of boards separately, and then remove them from the production line one by one. The production line efficiency is low and the production cycle is significantly reduced. Summary of the Invention

[0005] In view of this, the present invention provides a system and method for producing aerated concrete panels to solve the problem of low production efficiency of existing panels.

[0006] In a first aspect, the present invention provides an off-line system for aerated concrete panels, comprising: a first conveyor line and a second conveyor line, the first conveyor line and the second conveyor line being arranged side by side and both used for conveying panels along the off-line direction; a first clamping mechanism, arranged across the first conveyor line and the second conveyor line, the first clamping mechanism being adapted to place the panels on the first conveyor line and / or the second conveyor line; a second clamping mechanism, arranged across the first conveyor line and the second conveyor line and along the off-line direction, the second clamping mechanism being arranged downstream of the first clamping mechanism, the second clamping mechanism being adapted to transfer the panels between the first conveyor line and / or the second conveyor line; and a packaging mechanism, arranged between the first clamping mechanism and the second clamping mechanism, adapted to package the panels.

[0007] Optionally, the unloading system also includes a flipping mechanism, which is located downstream of the first conveyor line along the unloading direction of the sheet material.

[0008] Optionally, the flipping mechanism includes a frame, a first flipping frame and a second flipping frame. Both the first flipping frame and the second flipping frame are rotatably connected to the frame. Along the down-line direction of the sheet material, the first flipping frame is arranged adjacent to the downstream of the first conveyor line, and the second flipping frame is arranged side by side on one side of the first flipping frame.

[0009] Optionally, along the unloading direction of the sheet material, the unloading system includes a stacking station, a packaging station, and a stacking station arranged in sequence, with a first clamping and lifting mechanism set at the stacking station, a packaging mechanism set at the packaging station, and a second clamping and lifting mechanism set at the stacking station.

[0010] Optionally, a lowering station is also provided downstream of the stacking station along the unloading direction of the sheet metal. The first conveyor line is provided with four sections, which are suitable for independent operation and are sequentially extended to the stacking station, packaging station, stacking station and lowering station. The second conveyor line is provided with three sections, which are suitable for independent operation and are sequentially extended to the stacking station, packaging station and stacking station.

[0011] Optionally, two packaging mechanisms are provided, with the two packaging mechanisms respectively located on one side of the first conveyor line and the second conveyor line.

[0012] Optionally, the unloading system also includes a third conveyor line, with the first clamping mechanism spanning the first, second, and third conveyor lines. The third conveyor line is adapted to transport the produced sheet metal to below the first clamping mechanism for unloading.

[0013] Optionally, the first conveyor line and the third conveyor line are arranged adjacent to each other, and the second conveyor line is located on the side of the first conveyor line away from the third conveyor line.

[0014] Secondly, the present invention provides a method for removing aerated concrete panels from the production line, for use in the aerated concrete panel production line system as described above. The method includes the following steps: stacking: a first clamping and lifting mechanism places the first half-stack and the second half-stack of panels onto the first conveyor line and the second conveyor line respectively; packaging: packaging the first half-stack and the second half-stack; stacking: a second clamping and lifting mechanism transfers the second half-stack from the second conveyor line and places it above the first half-stack on the first conveyor line; removing from the production line: removing the first half-stack and the second half-stack from the production line.

[0015] Optionally, the aerated concrete panel unloading system also includes a flipping mechanism, which is located downstream of the first conveyor line along the unloading direction of the panels; the unloading method further includes the step of flipping after the stacking step and before the unloading step: flipping: the flipping mechanism flips the first half-stack and the second half-stack by 90°.

[0016] Using the technical solution of the present invention, the first clamping and lifting mechanism can place the first half-stack of the whole stack of boards on the first conveyor line and place the second half-stack of the whole stack of boards on the second conveyor line to realize the unpacking of the whole stack of boards; then the first half-stack and the second half-stack are packaged respectively; after the packaging is completed, the second clamping and lifting mechanism can transfer the packaged first half-stack and the second half-stack to the same conveyor line to realize the stacking of the first half-stack and the second half-stack.

[0017] Therefore, the aerated concrete panel production line system and method of the present invention can realize the process of dividing and packaging whole stacks of panels, then stacking them together into whole stacks of panels, and then unloading the whole stack of panels together. The production line cycle is fast, which greatly improves the production efficiency of aerated concrete panels. Moreover, the aerated concrete panel production line system configured in this way has a simple structure, can be implemented using conventional equipment, has low production input, and saves construction costs.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0029] According to an embodiment of the present invention, in one aspect, an aerated concrete panel unloading system is provided, including a first conveyor line 1, a second conveyor line 2, a first clamping mechanism 4, a second clamping mechanism 5, and a packaging mechanism 6.

[0030] The first conveyor line 1 and the second conveyor line 2 are arranged side by side, both used to convey the sheet material along the downward direction of the conveyor line. A first clamping mechanism 4 is arranged across the first conveyor line 1 and the second conveyor line 2, and is adapted to place the sheet material on the first conveyor line 1 and / or the second conveyor line 2. A second clamping mechanism 5 is arranged across the first conveyor line 1 and the second conveyor line 2, and is located downstream of the first clamping mechanism 4 along the downward direction of the conveyor line. The second clamping mechanism 5 is adapted to transfer the sheet material between the first conveyor line 1 and / or the second conveyor line 2. A packaging mechanism 6 is arranged between the first clamping mechanism 4 and the second clamping mechanism 5, and is adapted to package the sheet material.

[0031] like Figure 1 and Figure 4 As shown, in the production line system for aerated concrete panels of the present invention, during actual production, the first clamping and lifting mechanism 4 is set across the first conveyor line 1 and the second conveyor line 2. Therefore, the first clamping and lifting mechanism 4 can place the first half-stack 110 of the whole stack of panels 100 on the first conveyor line 1 and place the second half-stack 120 of the whole stack of panels 100 on the second conveyor line 2, thereby realizing the stacking of the whole stack of panels 100. After the packaging mechanism 6 packages the first half-stack 110 and the second half-stack 120 respectively, the second clamping and lifting mechanism 5 is set across the first conveyor line 1 and the second conveyor line 2. Therefore, the second clamping and lifting mechanism 5 can transfer the packaged first half-stack 110 to the second conveyor line 2 or transfer the second half-stack 120 to the first conveyor line 1, thereby realizing the stacking of the first half-stack 110 and the second half-stack 120.

[0032] Therefore, the aerated concrete panel production line system of the present invention can divide and package 100 panels into smaller stacks, then stack them back into a single stack of 100 panels, and finally unload the entire stack of 100 panels together. This results in a fast production cycle and significantly improves the production efficiency of aerated concrete panels. Moreover, this aerated concrete panel production line system has a simple structure, can be implemented using conventional equipment, has low production investment, and saves on construction costs.

[0033] It should be noted that, as Figure 1 As shown, direction A is the downward direction of the aerated concrete panels. On the first conveyor line 1 and the second conveyor line 2, the panels flow along direction A. The first conveyor line 1 and the second conveyor line 2 can be chain conveyors, belt conveyors, or roller conveyors, etc. This application does not specifically limit these, as long as they can achieve the function of the aerated concrete panels flowing along the downward direction.

[0034] The first clamping mechanism 4 may include a frame spanning the first conveyor line 1 and the second conveyor line 2, and a robotic arm movably mounted on the frame. Specifically, above the first conveyor line 1 and the second conveyor line 2, the robotic arm is vertically movable on the frame to grasp or place the sheet metal; and in the parallel direction of the first conveyor line 1 and the second conveyor line 2, the robotic arm is horizontally movable on the frame to move between the first conveyor line 1 and the second conveyor line 2, thereby placing the sheet metal on the first conveyor line 1 or the second conveyor line 2.

[0035] The second clamping mechanism 5 is similar in structure to the first clamping mechanism 4. It also uses the up-and-down movement of the robotic arm to grab or place the plate, and the left-and-right movement of the robotic arm to transfer the plate between the first conveyor line 1 and the second conveyor line 2. This will not be described in detail here.

[0036] Preferably, the first clamping and lifting mechanism 4 is a single-mold clamping and lifting machine, and the second clamping and lifting mechanism 5 is a plate stacking and lifting machine.

[0037] The packaging mechanism 6 can be a sling-type packaging machine. The first conveyor line 1 and the second conveyor line 2 have a through-space, through which the packaging strapping passes and bundles the sheet material. For example, the first conveyor line 1 and the second conveyor line 2 are roller conveyors, with multiple sets of rollers spaced apart along their extension direction, forming the aforementioned through-space between adjacent rollers. It is understood that the first conveyor line 1 and the second conveyor line 2 can also employ other conveying methods, as long as they can cooperate with the packaging mechanism 6 to complete the packaging operation of the sheet material.

[0038] In some embodiments, two packaging mechanisms 6 are provided, and the two packaging mechanisms 6 are respectively provided on one side of the first conveyor line 1 and the second conveyor line 2 to package the plates on the first conveyor line 1 and the second conveyor line 2 respectively, so as to ensure packaging efficiency.

[0039] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the unloading system also includes a flipping mechanism 7, which is located downstream of the first conveyor line 1 along the unloading direction of the boards. In this embodiment, after the stack of boards 100 completes the stacking, packaging, and merging processes on the first conveyor line 1 and the second conveyor line 2, it can flow into the flipping mechanism 7 on the first conveyor line 1 to flip the stack of boards 100 off the line, avoiding damage to the boards due to prolonged pressure. Furthermore, in this embodiment, the boards enter the flipping mechanism 7 after being stacked into a whole stack of boards 100, eliminating the need for merging on the flipping mechanism 7, thus simplifying the flipping mechanism 7 and further reducing the equipment investment cost.

[0040] It is understood that in this embodiment, the second clamping mechanism 5 clamps and places the plates of the second half-stack 120 on the second conveyor line 2 above the plates of the first half-stack 110 on the first conveyor line 1, so that the first half-stack 110 and the second half-stack 120 are stacked together on the first conveyor line 1, so that the stacked plates 100 can continue to flow to the flipping mechanism 7.

[0041] Specifically, in this embodiment, it is possible to achieve the following, such as Figure 1 and Figure 3 As shown, the flipping mechanism 7 includes a frame 71, a first flipping frame 72, and a second flipping frame 73. Both the first flipping frame 72 and the second flipping frame 73 are rotatably connected to the frame 71. Along the direction of the aerated concrete panels' unloading, the first flipping frame 72 is arranged adjacent to the downstream of the first conveyor line 1, and the second flipping frame 73 is arranged side by side on one side of the first flipping frame 72. During the unloading operation of aerated concrete panels, the first flipping frame 72 is in a horizontal state. The stacked panels 100 are conveyed by the first conveyor line 1 to the first flipping frame 72. The first flipping frame 72 rotates 90° relative to the frame 71, thereby causing the stacked panels 100 to flip 90° and place the stacked panels 100 on the second flipping frame 73. At this time, the first flipping frame 72 is in a vertical state, and the second flipping frame 73 is in a horizontal state. Then, the first flipping frame 72 can rotate in the opposite direction to return to a horizontal state, and the next stack of boards 100 to be flipped can continue to flow into the first flipping frame 72. The second flipping frame 73 remains in a horizontal state until the stack of boards 100 after the previous flipping is completed and removed from the production line.

[0042] With this flipping mechanism 7 configured in this way, after the first flipping frame 72 completes the flipping operation of the previous stack of boards 100, the next stack of boards 100 to be flipped can continue to flow into the first flipping frame 72. It does not interfere with the unloading operation of the previous stack of boards 100, reducing the waiting time for flipping operations and further improving the unloading efficiency.

[0043] It should be noted that the first tilting frame 72 and the second tilting frame 73 are independently mounted on the frame 71, and the included angle between them can be any angle within the range of 0-180°. For example, both the first tilting mechanism 7 and the second tilting mechanism 7 can be rotatably connected to the frame 71 by means of a cylinder, a hydraulic cylinder, or an electric drive structure, etc., and this application does not make any specific limitations on this.

[0044] Furthermore, in the direction perpendicular to the unloading direction of the sheet metal, the second tilting frame 73 is provided with multiple support frames 731 at intervals. It is understood that after the sheet metal is tilted, it is placed on the support frames 731. The intervals between the support frames 731 facilitate the removal of the sheet metal from the second tilting frame 73 by forklifts or other unloading trolleys. Moreover, the multiple support frames 731 on the second tilting frame 73 can accommodate sheet metal of various specifications.

[0045] For example, the support frame 731 is provided with 6 units, which can be used for the flipping and unloading of stacks of boards 100 with a length of 1.8m-6m.

[0046] Furthermore, in the direction perpendicular to the bottom of the board, the first flipping frame 72 is provided with multiple idler rollers and a motor that drives the idler rollers to rotate. The motor drives the idler rollers to rotate, thereby moving the stack of boards 100 on the first conveyor line 1 onto the first flipping frame 72. For example, the spacing between the idler rollers on the first flipping frame 72 is smaller than the spacing between the support frames 731 on the second flipping frame 73.

[0047] In some embodiments not shown in the figures, the flipping mechanism 7 may also be located downstream of the second conveyor line 2. After the first half-stack 110 and the second half-stack 120 are stacked together on the second conveyor line 2, they are transferred to the flipping mechanism 7.

[0048] Furthermore, in some embodiments, such as Figure 1 and Figure 2Along the unloading direction of the boards, the unloading system includes a stacking station 10, a packaging station 20, and a stacking station 30 arranged sequentially. A first clamping and lifting mechanism 4 is located at the stacking station 10, a packaging mechanism 6 is located at the packaging station 20, and a second clamping and lifting mechanism 5 is located at the stacking station 30. In this unloading system, the first clamping and lifting mechanism 4 performs stacking operations of the entire stack of boards 100 at the stacking station 10, the packaging mechanism 6 performs packaging operations of the first half-stack 110 and the second half-stack 120 at the packaging station 20, and the second clamping and lifting mechanism 5 performs stacking operations of the first half-stack 110 and the second half-stack 120 at the stacking station 30. The operations of the three stations are independent of each other and can be carried out simultaneously without affecting the cycle time, further improving the unloading efficiency of the boards.

[0049] It should be noted that the interval between the stacking station 10 and the stacking station 30 should be greater than the length of the sheet material to ensure that each station can operate independently. For example, if the length of the sheet material is 6m, the interval between the stacking station 10 and the stacking station 30 should be greater than 6m. It is understood that the interval between the first clamping mechanism 4 and the second clamping mechanism 5, which are respectively set on the stacking station 10 and the stacking station 30, should also be greater than the length of the sheet material.

[0050] Furthermore, downstream of the stacking station 30, a discharging station 40 is also provided along the discharging direction of the boards. The first conveyor line 1 extends to the stacking station 10, the packaging station 20, the stacking station 30, and the discharging station 40. It is understood that in this embodiment, at the stacking station 30, the first half-stack 110 and the second half-stack 120 are finally stacked onto the first conveyor line 1. Thus, the first conveyor line 1 extends to the discharging station 40, where the entire stack of boards 100 is discharging, avoiding interference with the operations of other stations and ensuring the discharging cycle time.

[0051] Furthermore, in this embodiment, as Figure 1 and Figure 2 As shown, the second conveyor line 2 extends to the stacking station 10, the packaging station 20, and the stacking station 30. In other words, the second conveyor line 2 does not extend to the unloading station 40 to avoid affecting the unloading operation of the first conveyor line 1.

[0052] For example, in some embodiments, both the first conveyor line 1 and the second conveyor line 2 can be segmented. Specifically, the first conveyor line 1 has four segments, which extend sequentially within the stacking station 10, the packaging station 20, the stacking station 30, and the unloading station 40, and the four segments can operate independently of each other. The second conveyor line 2 has three segments, which extend sequentially within the stacking station 10, the packaging station 20, and the stacking station 30, and the three segments can operate independently of each other. The length of each segment of the first conveyor line 1 or each segment of the second conveyor line 2 depends on the length of the sheet material, as long as the length of each segment is greater than the length of the sheet material, and the interval between adjacent segments is less than the length of the sheet material.

[0053] Furthermore, in this embodiment, the flipping mechanism 7 is located in the unloading station 40 and is connected to the downstream of the first conveyor line 1. In actual production, the unloading operation of the whole stack of boards 100 can be carried out directly on the first conveyor line 1 of the unloading station 40, or the unloading operation of the whole stack of boards 100 can be carried out on the flipping mechanism 7 after the flipping mechanism flips the whole stack of boards 100.

[0054] like Figure 1 and Figure 2 As shown, the unloading system of the present invention also includes a first trolley 81 and a second trolley 82. The first trolley 81 is used to unload the stack of boards 100 from the first conveyor line 1, and the second trolley 82 is used to unload the boards from the flipping mechanism 7. For example, the first trolley 81 and the second trolley 82 are forklifts, and multiple vehicles of both the first trolley 81 and the second trolley 82 can be provided to improve unloading efficiency.

[0055] In some embodiments not shown in the figures, both the first conveyor line 1 and the second conveyor line 2 can extend to the unloading station 40, so that the unloading can be selected on the first conveyor line 1 or the second conveyor line 2 as needed.

[0056] Furthermore, in some embodiments, such as Figure 2 As shown, the unloading system also includes a third conveyor line 3. A first clamping mechanism 4 is arranged across the first conveyor line 1, the second conveyor line 2, and the third conveyor line 3. The third conveyor line 3 is adapted to transport the produced panels to the area below the first clamping mechanism 4 for unloading. In the unloading system of this embodiment, the first clamping mechanism 4 can be connected to the aerated concrete panel production line through the third conveyor line 3, ensuring the continuity of production and unloading.

[0057] It should be noted that, as Figure 2As shown, direction B is the conveying direction of the sheet material on the third conveyor line 3. Along the conveying direction B of the sheet material on the third conveyor line 3, a finished product splitting crane 92 and a splitting machine 91 are sequentially arranged, with the first clamping mechanism 4 located downstream of the splitting machine 91. The finished product splitting crane 92 is used to transfer the finished aerated concrete sheet material from the production line to the third conveyor line 3, and the splitting machine 91 is used to separate the finished aerated concrete sheet material that has been bonded together after steam curing, layer by layer. In this embodiment, both the finished product splitting crane 92 and the splitting machine 91 can be existing conventional equipment, which will not be described in detail here.

[0058] Furthermore, in this embodiment, the first conveyor line 1, the second conveyor line 2, and the third conveyor line 3 are arranged side by side, with the first conveyor line 1 and the third conveyor line 3 adjacent to each other. The second conveyor line 2 is located on the side of the first conveyor line 1 away from the third conveyor line 3. The first conveyor line 1 extends to the stacking station 10, the packaging station 20, the stacking station 30, and the unloading station 40, while the second conveyor line 2 extends to the stacking station 10, the packaging station 20, and the stacking station 30. Thus, at the unloading station 40, the second conveyor line 2 provides working space for the unloading operation of the first conveyor line 1, making reasonable use of the factory layout space and resulting in a more compact structure.

[0059] According to an embodiment of the present invention, in another aspect, a method for removing aerated concrete panels from the production line is also provided, applied to the aerated concrete panel production line system as described in the above embodiments. Specifically, the method includes the following steps:

[0060] Stacking step: The first clamping and lifting mechanism 4 places the plates of the first half-stack 110 and the second half-stack 120 onto the first conveyor line 1 and the second conveyor line 2 respectively;

[0061] Packaging steps: Pack the first half-stack 110 and the second half-stack 120;

[0062] Stacking step: The second clamping and lifting mechanism 5 transfers the second half-stack 120 on the second conveyor line 2 and places it above the first half-stack 110 on the first conveyor line 1;

[0063] Offline steps: Remove the first half-stack 110 and the second half-stack 120 from the production line.

[0064] In this embodiment, using the aerated concrete panel unloading method of the present invention, in the stacking step, the first clamping and lifting mechanism 4 places the first half-stack 110 and the second half-stack 120 of the whole stack of panels 100 onto the first conveyor line 1 and the second conveyor line 2 respectively, thereby realizing the stacking of the whole stack of panels 100; then in the packaging step, the first half-stack 110 and the second half-stack 120 are packaged respectively; after the packaging step is completed, the second clamping and lifting mechanism 5 transfers the packaged second half-stack 120 from the second conveyor line 2 to the first half-stack 110 of the first conveyor line 1, thereby realizing the stacking of the first half-stack 110 and the second half-stack 120 together.

[0065] Therefore, the method for removing aerated concrete panels from the production line of the present invention can realize the process of dividing and packaging a whole stack of panels 100 into separate stacks, then stacking them together into a whole stack of panels 100, and then removing the whole stack of panels 100 together from the production line. The production line cycle is fast, which greatly improves the production efficiency of aerated concrete panels.

[0066] More specifically, in some embodiments, during the stacking step, such as Figure 4 As shown, the specific steps include:

[0067] The first clamping and lifting mechanism 4 clamps up the second half-stack 120 located at the top of the whole stack of boards 100 and places it on the second conveyor line 2. The second conveyor line 2 drives the second half-stack 120 to continue to flow along the lower line direction of the boards.

[0068] The first clamping and lifting mechanism 4 clamps up the first half-stack 110 located at the bottom of the whole stack of boards 100 and places it on the first conveyor line 1. The first conveyor line 1 drives the first half-stack 110 to continue to flow along the lower direction of the boards.

[0069] In the packaging step, there are two packaging mechanisms 6. The two packaging mechanisms 6 can package the first half-stack 110 on the first conveyor line 1 and the second half-stack 120 on the second conveyor line 2 respectively. The two packaging mechanisms 6 can operate independently and do not affect each other.

[0070] Understandably, after the above-mentioned stacking steps, the second half-stack 120 on the second conveyor line 2 first flows into the packaging mechanism 6 to complete the packaging.

[0071] The stacking process specifically includes the following steps:

[0072] The second clamping and lifting mechanism 5 picks up the second half-stack 120 after packaging and transfers it above the first conveyor line 1;

[0073] When the first half-stack 110 after packaging is placed directly below the second half-stack 120, the second clamping and lifting mechanism 5 places the second half-stack 120 on the first half-stack 110. The first half-stack 110 and the second half-stack 120 together form a whole stack of boards 100.

[0074] In the unpacking process, the first trolley 81 transports the packaged stack of boards 100 forks off the production line.

[0075] Furthermore, in some embodiments, the aerated concrete panel unloading system further includes a tilting mechanism 7, which is located downstream of the first conveyor line 1 along the unloading direction of the panels. Correspondingly, in the above unloading method, after the stacking step and before the unloading step, the following step is also included:

[0076] Flipping step: Flipping mechanism 7 flips the first half stack 110 and the second half stack 120 by 90°.

[0077] In this embodiment, after the first half-stack 110 and the second half-stack 120 complete the stacking step, the flipping step is performed. There is no need to stack the first half-stack 110 and the second half-stack 120 within the flipping step, which simplifies the flipping mechanism 7 and improves the flipping efficiency, thereby improving the production line efficiency.

[0078] In this embodiment, after the flipping step is completed, in the unloading step, the second trolley 82 forks the flipped stack of boards 100 off the production line.

[0079] In some embodiments not shown in the figures, the first clamping and lifting mechanism 4 may also employ dual robotic arms in the stacking step to simultaneously place the first half-stack 110 on the first conveyor line 1 and the second half-stack 120 on the second conveyor line 2, so that both flow into the next process and are packaged at the same time.

[0080] Furthermore, during the stacking process, the first half-stack 110 of the first conveyor line 1 is in a waiting state until the second clamping mechanism 5 picks up the second half-stack 120 on the second conveyor line 2 and places it above the first half-stack 110. Then, the first conveyor line 1 drives the stacked whole stack of boards 100 to continue to flow.

[0081] Of course, in other embodiments not shown in the figures, during the stacking step, the first half-staple 110 on the first conveyor line 1 can be transferred and placed on top of the second half-staple 120 on the second conveyor line 2 to achieve stacking of the first half-staple 110 and the second half-staple 120.

[0082] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by the appended claims.
